TECHNICAL FIELD

The invention pertains to the field of toy products, and specifically pertains to a three-mode toy gun.

BACKGROUND

Toy guns are popular among children and young people and are commonly used in games and sports activities such as hunting games, fighting or war games. Toy guns are generally designed to resemble real guns and are also provided with glare and sound effects to create a sense of reality, thus making the toy gun more attractive to players.

Existing toy guns are generally divided into three types, the first type is a purely manual gun that requires a user to manually pull an air cylinder to a tail portion of the gun shell to snap on and fix the air cylinder. When it is desired to fire a bullet, the trigger is manually pressed to trigger the toy gun to execute the firing action. The second is a single-action toy gun. When the player presses the trigger once, the toy gun fires once, and can not continuously fire. The third type is an automatic toy gun When the player presses the trigger, the Toy gun will continuously execute the firing action, and can continuously fire bullets. The existing toy guns typically have only one or two modes because of the complexity of the structure and the difficulty of integrating the three modes on the same toy gun. There are few toy guns on the market that integrate the three modes simultaneously.

In view of this, the invention is proposed.
